Susan,
As I understand it, you don't really do multiple activations. You do one activation that incorporates the direction's number in it. For instance, if you are activating with something golden in the South, you might place a bowl with 9 golden coins in it, but if the golden activation is for the Northwest, you would use 6 coins. If your activation calls for a wind chime in the Northwest, you might hang one with 6 cylinders on it, but look for one with 8 to hang in the Northeast, etc. When my activations call for a crystal in the North, I place one there. But when such an activation is needed in the West, I get a little bag and put seven little crystals in it. At least that's what I understand about it.
May you create positive energy in your day.
